How does it work?

Since Apple Notes doesn't have any direct API access, browser can't directly talk to apple notes. Given that limitation, capturing web content to apple notes is a two part process as described below. It is all seamless to you once you have the app and the browwer extension installed.

Part 1: Capture the web content using the web clipper. This is what you would install from the chrome or firefox extension marketplace.

Part 2: Clipper sends data to the bridge application, that is invoked by the web clipper, and that sends data to apple notes.

All of this is done automatically for you (after installing both parts), and all your data belongs to you. We don't grab any data in any of this process. Data is sent locally from browser to bridge app, and then to apple notes, and no where else.
